Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166492, here are decompositions:

5 + 166487 = 166492
83 + 166409 = 166492
89 + 166403 = 166492
173 + 166319 = 166492
191 + 166301 = 166492
233 + 166259 = 166492
449 + 166043 = 166492
461 + 166031 = 166492

Showing the first eight; more decompositions exist.
